Pressure test of PE steel mesh skeleton

When the equipment system for the pressure test of the PE steel wire mesh skeleton is stable, increase the pressure to 1.5 times the working pressure, stabilize the pressure for 1 hour, carefully observe the pressure gauge, and patrol along the line, if there is no visible leakage during the test or A significant pressure drop occurs. When welding the replaced electric fusion pipe fittings, be sure to keep the inside of the pipe free of water, otherwise it will be difficult to weld the electric fusion pipe fittings firmly. After the welding is completed, it must be allowed to cool for more than 120 minutes before passing water for pressure test.

The physical and mechanical properties of the film or monofilament stretched by the PE steel mesh skeleton will be greatly improved in the stretching direction. Steel mesh skeleton composite pipe is a new type of pipe that is more popular in modern times. It has good technology and material. The heating time, heating temperature, connection pressure, and cooling time of the PE steel mesh skeleton are not strictly controlled according to the regulations. Moving or applying force to the connection before it has cooled completely. When using qualified raw materials to make technical products, the color of the welder's cutting strips should be brighter, and it is not easy to break when folded after repeated use.



The pipe connection management methods are all required to be the same material grade, pipe and pipe, pipe and pipe fittings of the same material, and the application of electric melting can be wider. In the maintenance of PE water supply pipes, if only some sand holes or other directly applied flange gate valves can be maintained. However, when the broken part of the PE water supply pipe is large, the following methods can be used to solve the problem.

The thinner the outer diameter of the PE steel mesh skeleton, the cheaper the corresponding price. In addition to the less material required for production, the transportation cost of such products is also low. In terms of traffic, it can fully meet the needs of ordinary families. The results show that although the expansion degree of PE steel mesh skeleton is higher, the stress caused by expansion is significantly smaller. Therefore, in the process of laying the PE steel mesh skeleton, it is necessary to eliminate the axial deformation caused by the seasonal temperature.
